VALVE. V

Specification of Letters Patent.

Application filed March 15, 1920; Serial No. 365,919.

To all whom it may concern:

Be it known that I, ELMER-H. SPENCER, citizen of the United States, residing at Nederland, in the county of Jefferson and State of-Texas, have invented certain new and useful Improvements inValves; and I do hereby declare the following to: be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same. I

i such exposure become'worn and leakyl 'Another objectof this invention is the provision of a valve wherein the surfaces which effect the closing of the valve are entirely removed from the substance passmg through the valve and thus eliminates serious difliculties which have been found in the old type of valve where a portion of the surface necessary to close the old type of valves is exposed to the moving substance and in Another object of the present invention is the provision of a disk type valve which includes means for retaining the valve members in. close contact with one another so as to permit no space between the two members and thus eliminate the gathering of sediment b ers. V I r A further object of the invention is'th'e provision of a'valve of this type wherein the valve itself may be arranged within a tank or still and submerged Y in the liquid contained within said tank' or still and thus eliminate any danger of the same becoming broken or damaged through accident, which generally occurs with the old type of valve arranged upon the exterior of a tank or still;

With the above and other objects in view, the invention consists in the construction, the combination and, arrangement of parts or foreign substances between the twomem,

irat nteaaui s, 1921i hereinaftermore fully set forth, pointed out in the claims and shown inithe accompany ingzdrawings in which, 7

F 1g. 31s a detailed perspective view of the valve .members in disassembled relation,

parts thereof being broken away and illus: I

tratedinsection. In the drawings accompanying this description, I have illustrated the valve as attached to a tee coupling, generally indicated by the numeral 1, having extended from one end thereof the outlet pipe 2' which is pro vlded with a reducer 3. The body 4 of the reducer 3 is threaded and connected therewith is a pipe coupling. or sleeve-6 which forms the valve chamber. Thetee coupling 1 is provided as herein illustrated witha reducing plug 7 and connected to'this reduc lng plug'is adraw-olf pipe 8through which the liquid contained within the tank, to

bedispensed. The valve proper'includes the stem-'9, the inner end of which is provided preferably with two enlarged threaded portionsYgenerwhich my improved valve is applied, may

. ally indicated by the numerals 1O and 11;

and arranged between these threaded portions is a rectangular shoulder 12 upon which is mounted 'the'valve body or disk '13;

This valve disk 13 is preferably of cylindrical formation, provided upon one side of its center with an arcuate port'or opening 14 which is adapted'to correspond with as1milarportor opening 15 formed in the valve seat 1'6; This valvedisk 13 'is-centrally pro-,

vide'd Zwith asubstantially rectangular sleeve adapted to t be engaged over the" shoulder 14 whereby the disk is rotated-through the turning movement of the valve'stem 9 and causedto slide, rotatably, upon the seat to closed or opened position.

"The valve seat 16 which is substantially cylindrical in form is; provided upon its exterior face with screw threads adapted to conform with the screw threads: upon the interiorf the "coupling constituting -;the

valve chamber 6 and is further provided at the central portion with an inter orly threaded sleeve 17' which is adapted for engagement with the threaded portions 10 or. 7

11 on the inner end of the valve stem.v

LM-ounted upon one of the threaded portions of'the valve stem 9 are the locking nuts 18 and '19 having arranged therebetween a washer 20 as illustrated in Fig. 1.

' 21 will normally retain the valve disk 13' It will be noted that the lock nut 18 is 01' substantially the size of the sleeve formed upon the central portion of the valve disk 14: and mounted upon this sleeve and the lock nut 18 is a coil spring 21, one end of which bears against the washer 20, while the other end thereof bears against the valve disk 13 so as to normally retain the valve disk in close contact with the valve seat 16.

The outer end of the valve stem :9 extends through a guide sleeve or standard bonnet 22 and at the outer end of the valve stem, 1 provide a substantially rectangular-portion 23'adapted to accommodate a handle (not shown). It will be noted that in Fig. 1, the

valve member is shown in an open position so that the liquid can readily pass through the openings ltand 15 and thence outwardly through the outlet pipe 2 where it will be directed, by means of the tee 1 into the outlet pipe 8. It will be noted from this, that the parts of the valve which ellectits closin-g are not exposed to the motion of the liquid and in order toclose the valve, it is simply necessary to give the stem 9 a half turn so that the solid portion of the valve body or disk 13 is moved into a. closing position over the opening 15 in the valve seat 16. It will also be noted that the coil spring in close contact with the valve seat 16 so as to prevent any sediment or foreign substances from becoming engaged between the valve members.

It is to be understood that the two threaded portions 10 and ll on the valve stem 9 permit the valve disk 13 and valve seat 16 to be readily reversed in their positions, that is, the valve seat 16 canbe en-' gaged by the threaded portion 11 and the lock nuts 18 and 19 engaged upon the threaded portion 10, thus reversing the position of the'valve disk so that the latter is arranged upon the inner face of the valve seat; also, that the valve seat 16 may bare. versed it required. It may be stated here that when the valve disk 13 is arranged upon the inner face of the valve seat 16,

. the coil spring 21 can be done away withif that when they are brought to a closed position, they will provide a secure tight-fitting oint. I i

.Fromthe above description, taken in conwill be readily apparentthat I have pro vided an extremely simple .v'alve which is to be located upon the interior oftanks stills or the like and submerged within the liquid contents of the tank and thus doing away with the old type of valve which is, generally arranged'upon the exterior of the tank.

be understood that these may beconverted I to suit the convenience to which the valve. is to be applied. 1 i
